Zevi Eckhaus accounted for two touchdowns, and Washington State clinched bowl eligibility in coach Jimmy Rogers' inaugural season with a 32-8 victory over Oregon State on Saturday night in a rare regular-season rematch for the only members of the Pac-12 Conference. Oregon State beat Washington State 10-7 at home on Nov. 1. The Cougars won both games in 1945 the last time the teams played twice in the same year.
